The Demand for Health Insurance: Risk, Markets, and the Limits of Choice

You wake before your alarm on a Tuesday in March. The apartment is quiet except for the sound of your wife, Valentina, moving carefully around the kitchen, seven months pregnant and already thinking about breakfast. On the table, half-hidden under a coffee mug, is an envelope you have been avoiding for three days.

It is your annual renewal notice from Isapre Cruz Blanca, one of Chile's private health insurers. You are 34, a freelance graphic designer who has built a solid client list over six years. You are healthy. You run three mornings a week along the Mapocho River. You have never, in four years of holding this policy, filed a single claim.

The number on the renewal notice is 187,000 Chilean pesos per month. That is roughly 18% of your average monthly income, and the insurer has raised it again, up 9% from last year, citing rising medical costs across their risk pool. You do the arithmetic on the back of the envelope: over the past four years, you have paid approximately 8.3 million pesos in premiums and received zero in benefits.

The case for dropping the policy is almost embarrassingly strong. You are young and healthy. Chile has a public health system, FONASA, which would cover you for a fraction of the cost. The money you would save over the next twelve months could pay for the crib, the stroller, three months of diapers, and still leave a buffer in your savings account. Valentina is already enrolled in her employer's plan. You are, by any reasonable measure, a low-risk individual.

But Valentina is seven months pregnant. And you are self-employed, which means no sick days, no disability coverage, no employer backstop. If something goes wrong with you, the financial consequences land entirely on your household at the worst possible moment.

What do you do?

Keep the policy and absorb the cost, trusting that the coverage is worth something even if you never use it? Or cancel the policy, bank the savings, and bet on your own good health for another year?

Both choices have a logic that is hard to argue with. That tension is not an accident. It is the central problem of health insurance markets, and it has been driving policy debates, actuarial calculations, and individual kitchen-table decisions for as long as modern medicine has existed.
